METHOD OF PREPARING SILICATE ADHESIVE BOND Russian patent published in 2000 - IPC

FIELD: chemical industry. SUBSTANCE: amorphous silicon- containing material is subjected to mechanical and chemical treatment in 10-17 wt.% caustic soda solution at S:L ratio of 1:(2.5-3.5) at 25-50 C and atmospheric pressure for 4-8 h in ball mill. Method makes it possible to utilize effectively multi-ton dust waste resulting from amorphous microsilica (ferrosilicon) and to produce silicate adhesive bond used for making acid- resistant coatings, putties and mastics in chemical industry; heat-resistant (dense and porous) materials in metallurgy and heat and power engineering; gluing concrete products, brick, natural stone and finishing materials of different varieties in building industry. EFFECT: more efficient preparation method. 2 cl, 2 ex, 1 tbl
